...um... there are 135 chapters already... and the anime has barely gotten into the story of the manga... so there won't be any marriage (if there is any) for a long long time... and if they were to do a second season, then there would be plenty of episodes they could do because there is still a lot of story to cover :D
...hopefully this will not turn into a money issue with the studio and they will keep releasing the anime... and like what was commented before, Naruto is going well and has a numerous amount of episodes and so hopefully Skip Beat! will too
